I think it's worth considering "cache list" idea described in the
following presentation:
	http://nordu.dkuug.dk/NordU2000/papers/papers/th16-solaris8.pdf

Not only this does fix unnecessary paging caused by high filesystem
activity, this also eliminates artificial configuration parameters
like vm.{anon,file,exec}{min,max}, so it should fit more sorts of
workloads.

The other interesting point is that the Solaris presentation says
it does improve random file I/O performance, because it reduces
the load of kernel page scanner.

FWIW, not only Solaris, but also FreeBSD seems to have the cache list
since FreeBSD 2.0.5.
